Hello! Nice to be here!
I hope someone can help.
Seems to me my question is right in this forum.
I have sent BCH from my wallet to Bitfinex - exchange after the hard fork, to a Bitfinex BAB address. I saw the transaction on the blockchain and I guess the Bitcoins are now splitted. BSV are on the same address.
Can I gain again the control over BSV?
Thank you for guidance!
According to this page: https://www.bitfinex.com/posts/321
(date November 28, 2018) Bitfinex DOES NOT
replay BCH deposits (BCH transactions users send to their exchange accounts at Bitfinex).
Unless the wallet app you're using is broadcasting BCH transactions on both chains (which is possible), or unless someone else replayed (broadcasted on the other chain), your BSV should not have been sent to the new address (your address at Bitfinex). However, if you're certain that the your transaction (deposit at Bitfinex) sent both BCH
(or BCH ABC or BAB) and BSV
(or Bitcoin SV) please contact support Bitfinex for more support (as they are the owners of the address and the only ones is a position to help as bitcoin is a permissionless network). Btw, what explorer did you use to lookup your BSV?
If the BSV is still at your original address you'll be able to do as you please with it as long as you have the private key for that address (the keys are the same for each chain). Please be careful (exercise due diligence) when importing your private key / seed words / mnemonic into a wallet or other application or site which purports to support BSV. Once a third party has access to your private key they have access to all coins (e.g., BCH and BSV) at the address.
